This is pretty much the Republican Party in one tweet:
Today's Republican Party thinks the key problem America faces is out-of-control entitlement spending. But cutting entitlement spending is unpopular and the GOP's coalition relies heavily on seniors. And so they don't want to propose entitlement cuts. If possible, they'd even like to attack President Obama for proposing entitlement cuts. But they also want to see entitlements cut and will refuse to solve the fiscal cliff or raise the debt ceiling unless there are entitlement cuts.
You can see why these negotiations aren't going well.
